My present inventlon relates to lasting machines, and its'object is toimprove and I perfectithe lasting operation on boots or shoes. Inworking the upper leather overthe sole or insole of'a boot or shoe,particuabout the heel and toe.

larly at the toe and heel portion, ithas always been very difficult todraw'and stretch the upper leather so that all the wrinkles I will besmoothed 'out and the leather itself stretched evenly, smoothly andsatisfactorily always been present, either in lasting by I hand or byany machine, and it has been frequently necessary to re-last shoesaround the toe repeatedly to obtain proper results. A further difficultywith both the hand lasting and machine lasting hasbeen-that when pin--cers were employed the leather was apt to be a torn and undulystretched, while when wiper plates were utilized, the leatherwas notalways worked over into lasted position to an extent suflicient toremove all the stretch,

LAs'rING-MAoHINE.

Patented Dec. 17, 1918 mechanisms repeatedly, I am enabled to work orprogressively stretch the leather with but relatively slight pullingstrain, so that the most delicate and highly finished patent leather andupper leather will not be damaged.

I prefer to embody the present invention in a lasting machine of thegeneral type shown in my copending application Serial No. 790.003 filedSept. 16, 1913, wherein a novel form of means to secure a wiping-grip onthe upper is shown. It will be understood, however, that the side wipingmechanism above explained, may be advantageously employed in any lastingmachine which acts to pull the upper leather at substantially a singlepoint at a time, while said upper is being worked over the edge of thelast. Furthermore I prefer to embody the ,present invention in a machinewhere the lasting tacks may be driven at will, permitting a plurality ofside wiping, stretching and progressive leather working actions to occuruntil the stretch of the leather is fully taken out, and then to driveThe effect of these side wiping mechanisms is to work all the full nessor surplus leather into the best position to be acted on by the mainlasting device, so

that when the lasting ,tack is driven, the leather will have beenstretched to its utmost. Also this 'side wiping action and working ofthe leather may be performed repeatedly before the lasting tack isdriven, as these tacks are put in at the will of the operator. Also Imay vary the speed, tension and'wiping action of the side wipers, as maybe best suited for the particular work in hand. heavy upper leather onmens work for example, requiring more strain and tension than light kidfor womens work. My side wipers. particularly in a lasting machine ofthe type of mv said copending application. enable me to last a largevariety of stock with equal facility and without any danger of tearingthe same, not only light or heavy upper leathers, but canvas or clothfor shoes may also be lasted, satisfactorily. In a lasting machine usinga wiper I prefer to arrange the side smoothing or wiping mechanisms tobe actuated by the wiper bar itself and simultaneously therewith,serving bar and the side wiping mechanisms; and

ingat the rightf viewing Fig. 1, standards so 4 having suitab e journalbearingsfor the shafts 5 and6 and the respective cam wheels overhanginghead 7 terminating in a vertically arranged boss 8 adapted to receivethe vertically rejciprocable spindle 9 of the tack driving mechanism. Aside bracket 10 approximately at right angles to the frame3 is also;provided to support the tackhopper and raceway 121. Formed on springtension to actuate the lever 13 in its downward or driving action, andtherefore form a hub 16 on the pivot pin 12, and coil the spring 17about said hub, with the outer end of the spring engaging the lever 13,the other end 18 of said spring being held by a pin 19 on the arm 20,which arm is pivoted on the'pin 12, and may be secured to the hub 16 invariety of adjustable positions by a bolt 21 passing through the arm andengaging with holes 22 in said hub 16. This construction enables anadjustable tension to be secured on the spring 17. The arrangement ofcams on the shaft 6 is generally similar to that of my copendingapplication, the roll 15 being actuated by a cam to oscillate the lever13, lift the tack driving spindle 9, and whenthe cam-23 releases6110101115, the spring 17 acts to drive the tack. A pulle 24 is carriedby theshaft 6 and said sha t is preferably arranged with a clutchcontrolling the cam 23 and permitting but a single revolution of the camand, therefore, onetack driving operation to be carried outoneachdepression of a foot treadle by "the operator, in a usual manner.I

At the side of "the frame 3 is a plate 25 acting as a lateral guide fora hori zontally reciprocating wiper bar 26, which bar is given-a to andfro reciprocation by an eccentric 27 on the shaft 5 and an encirclingstrap 28, the latter having a socket '29 to which the bar 26 isconnected at 30'. The forward portion (if the bar 26 is pivoted to a.supporting link .31, :at 32', the lower end ofsaid link being pivotedat.33to a forwardly extending bracket .34 of the-frame Preferably Iemp'loyduplicate links 31; the pivot pin 32 assing throughasuitah'lebearing in the bar 26 and through both of the links which aresimilarly mounted :on the lower pin 33. To the forward end of the wiperbar 26 is attached :by a bolt 34, a wiper 35 having its ends forked at36 and 37 110 straddle the pincer and presseri3-8 and tack nozzle 39,this construction being generally "similar to that of the machine inmyfisai'd copending application. The to and fro reciprocation of thewiper bar26 caused-by the action of the eccentric rocks the bar 26on-the link 31 and manipulates the wiper prongs 36. and 37 to engage andWipe, rub, push, and smooth the up er leather offa shoe over the edge ofa last, so that a tack may be driven through the nozzle '39 to securethe leather so lasted and held by the presser 38 in its extreme workedover position. To embody my present invention of side wiping mechanismswhich will aid in working over the leather and will 'actto strain,stretch and work the'leather from either side of the wiper prongs towardthe point at which the tack may be or is to be driven, I attach to theforward end, of the wiper bar 26 a cross bar 40 by a bolt or screw 41,said cross bar having each end slotted, as shown in Fig. 1, toreceivethe side wiping bars 42 and 43 which are pivotally held by bolts44 and 45, respectively, see Fig. 6. These bars are provided with camslots 46 and 47 respectively, said cam slots being adapted to receivepins 48 and 49, each carried by a plate 50, one of which is secured toeach side of the frame 3 by screws 51. The inclination of the cam slots46 and 47 is at an angle suflicient to throw the outer ends of the sidewipers 42 and 43 inwardly, when the bar 26 moves forwardly, as shown indotted lines in Fig. 6, so that they will push and strain the leatherengaged thereby u nearly to the point where the lasting tac is driven.The result is that when the lasting tack is driven it will hold leatherin a- "la'sited' position, which leather has been Zthe lasting device,whether such device is grippers, wipers, or my lmproved form ofwiper-gripper, is substantially perpendicular to the edge portion of thelast being presented. Straining the leather in this direction,especially at the toe necessarily leaves more or less looseness ateither side of the working point, where the curvature of the lastpermits this looseness to accumulate; but by means of my side wipingdevices, this looseness is stretched and strained out of the stock and'direitlyup to the point at which the lasting tack is driven. I preferto form the forward wiping ends of the wiper prongs 36 and 37 withbeveled faces 52 see Fig. 1) the extreme end portions of each of thewiper prongs bemg downturned to form these beveled faces 52 and toprovide recesses behind said downturned ends which the ends of the sidewiper bars 42, 43 may enteras they approach each other, the wiper"prongs being then advanced over the shoe bottom to permit this. fWhilethe ends of t-he wipers l3 are in the recessesthey form continuations ofthe lower wiping faces of the wiper prongs 36, 37.

' "In embodying my present invention in a type of lasting machineemploying wipergrippers, as herein shown, I prefer to mount on the boss8 of the fixed frame portion of the machine, a block having a pair {ofvertical grooves 55 and 56 formed at either side of said block inposition to re-.

ceive arms 57 and 58, carrying gripping devices 59 and 60 respectively,which are adapted to cooperate with the wiping prongs 3G and 37respectively to constitute the wiping-grippers of the machine, themember 59 and wiper prong 37, for example, are adapted to cooperate ingripping the upper leather engaged between them and last the same. Iprefer to pivot the arms '57 and 53 at the upper portion of the block 1nthe respectivegrooves therefor, approximately as shown at 61 in Fig.1.The

' lower part of each arm 57 and 58 is provided with an offset 62 slottedto receive the shank of one of the gripper members 59, 60 which is heldin ad usted position by the aid of a set screw 63 bearing thereon, as

7 clearly shown in Fig. 4C. These arms 57 and with the respective wiperprongs adapted to 58 are each held in position to cooperate engagetherewith by springs 64 wrapped the pivot pm 451 at.

aid the euter'l end each arm,'as a fulcrum and with the upper end ofsaid spring arranged for adjustable tension by engagement with a screw65 that is threaded through the flange of a bracket 66 held to the block54. by a bolt 67 (see Fig. 1). In theoperation of the machine thereciprocation of the wiper bar 26 acts to force or wipe the leather ofthe shoe over the edge-0f the last until the underside of the upper isengaged by one of the cooperating gripper members 59 or 60, when the continued wiping movement ofthe wiper bar carries the cooperating gripperwith it, increasing the gripping strain on the upper leather through theforce of the spring 64 acting on the gripper member until the completionof the wiping action and the retraction of the wiper bar 26. in lastingshoes it is desirable to work over the upper in advance of the tackingmechanism, and

therefore in working down one side of a shoe, the gripper 60 isemployed, to cooperate with its respective wiper prong 36 and pull overthe upper leather just in advance of the tack driving nozzle, 39, whilein lasting the other side of the toe the gripper 60 is preferably thrownout and the gripper 59 is utilized in cooperating with its wiper prong37 to pull over the upper just in advance of the tack nozzle 39. Thesegrippers 59 and 60 may be adapted to be thrown out of or into operativeposition by any suitable means. In the present machine, however, Iprefer to employ automatic mechanism which will throw out a gripperatthe end of a predetermined number of tacking actions, while the wipingmovements continue. This tack driving mechanism is always under thecontrol of a treadle, and may be thrown into operation after thecompletion of the desired number of wiping actions, the automaticthrowing out of the gripper taking place after a predetermined number oftacks have been driven. T have found that it is feasible to permit thewiper gripping operations to be continuously performed, especially whenacting in conjunction with my side wiper mechanism, when lasting oneside of the toe of a shoe, until a suitable number of tacks have beendriven and then to throw out the gripper which has been working on thatside of the shoe,

and throw in the cooperating gripper for the other side to work down thetoe of the shoe on the opposite side thereof in a similar manner.

Accordingly, I have employed in the present machine automatic mechanismfor accomplishing this, result. The mechanism for automaticallyaffecting; one gripper, 60, for example, is identical with thataffecting the other gripper, 59., and the detailed description of oneapplies to the other also.

On the side of the frame 7 adjacent the gripper 6G horizontal bat-r68pivoted att69 to the arm 58, which arm carries the end engaged by thebar 70, a cam7 1. The axlej73 is extended suliiciently on the sideofthelmachine illustrated in Fig. 1, to constitute a'hub 75 (Fig. 4:)having a ratchet wheel 76 vkeyed thereto or formed integrally therewith.The hub portion 75 carries a sleeve 77 on which sleeve a cam 78, similarto the foam 74; is positioned, and a ratchet wheel 79 similar to theratchet 76 is secured to said cam by a screw 80. Also mounted n thesleeve 77 is a lever 81 carrying a pawl 82 pivoted to said lever at 83and adapted to be pressed by a spring 84 into engagement with the teethon the ratchet 79. The outer end of the lever 81 is forked to receive arod 85 connected with a foottreadle (not shown). A similar lever 86 ismounted on the hub 75 outside the ratchet 76, and a pawl 87 having aspring .89to force the .end of said pawl into engagement with the" teethof the ratchet 76. is provided, a rod- 90 being pivoted to this lever at91, and connected with another foot treadle, not shown. The rod 90carries a collar 92 and slides through a guide plate 93, a second collar94 being affixed to the rod underneath the guide plate 93 and aneXpansible spring 95 is coiled about the rod 90 between the guide plate93 and the upper collar 92, as'shown in Fig. 1; a similar arrangement isalso provided for the rod 85, so that these rods are normally held in anupward position, or are returned to upward position upon either beingdepressed by its foot treadle, to the limit permitted by the lowercollar 94: on the rod 90, as will be readily understood. Mounted on thehub 75 is a lever 96 carrying on each side a pawl 97, each pawl having aspring 98 adapted to hold its pawl normally in a predetermined positionwith relation to a stop 99, this lever being arranged to swing freely onthe hub 75 and one of said pawls 97 being arranged to engage the ratchet76 and the other the ratchet 79, the lever 96 being mounted betweenthese two ratchet wheels as clearly shown in Fig. 4. The lever 96 isoscillated bv a link 100 pivoted at 101 to a reciprocating; bar 102, thepivot 101 engaging a $l0t in the bar 107 to prevent vertical movement ofthe pivot. The bar 102 receives its' reciprocation from an eccentric onthe cam shaft 6, being actuated whenever a tack is driven. Each of theratchet wheels 76,. 79 is provided with series. of different teeth, oneseries of teeth being depre d o shor ened (see Fig. 5)

: as at 103 below the limit of engagement of the pawl 97 on the lever96, the stop 99 hold ing said pawl above the series of shorter teeth.The series of longer teeth indicated at 104 is adapted to be engaged bysaid pawl until interrupted at the series of .shorter teeth 103. Thepawls 82 and 87 however on the levers attached to the foot treadles.will swing-freely sufficiently to engage the series of shorter teeth103.. The @pawls '97 therefore,.will automatically act to rotate bothratchet wheels 76 and 79 until they reach the shorter "teeth 103 in eachwhen said ratchet wheels will stop. Either foot treadle, however, whendepressed, will cause the respective ratchet wheel actuated therecamrolls 105 and 106 in position "to be engaged respectively by the cams'78 and 74,

and the said cams are angularly positioned relatively with theirrespective ratchet ,wheelsso that the rods 68 and 70 are thrownforwardly and-the grippers 59 andv 60 are thrown out of operativeposition when a pawl 97 has reached a series of short teeth 103 ineither ratchet. Thus when the pawls 97 cease to act, the grippers 59"and60 are thrown and held out of operative position at the end of as manytack driving actions as there are teeth in one of the series 104 of longteeth in the ratchet wheels 76, 79. The tracker can always be usedindependently of the wiper gripping movements whenever the operatordesires and on the completion of apredetermined number of tackingoperations (shown as 10) the grip per (59 or 60) then in use will bethrown out of operation. The operator is then able to employ thecontinuously operating wipers alone in connection with the tackingmechanism, operable at will.

A presser and pincer 38 is carried on a reciprocatingbar 107 whichslides between the frame 3 and one of the plates 50 at the front of themachine and beneath a plate 108 at the rear of the frame 3, beingactuated by a bell crank lever pivoted at 109, having one arm 110engaging a stud 111 on the bar 107, and the other arm 112 carrying a camroll 113 in position to be rocked by a cam on the shaft 6. A spring 114.holds the roll 113 in engagement with the cam on the shaft 6. Thereciprocating presser 38 assists in holding the leather in position isabout to be driven.

I also provide a pincer jaw 115 adjustably mounted on one arm 116 of arock shaft 150 mounted in a holder 117 formed as a branch or part of thebar 107. The other arm 152 of the rock shaft 150 carries a block 153pivoted there to, through which extends loosely a rod 154. The rod 154is connected at its rear end to the pivot 101 for actuation by the bar102 and carries two adjustable collars 155, 156. On the rod 154 betweenthe collar 156 and the block 153 is a spring 157. When the rod 154 isreciprocated the collar 155 acts positively to move the pincer jaw 115outwardly away from the pincer member 38 and the collar 1 56 actsyieldingly through the spring 157 to move the jaw 115 in wardlycoincidently with the forward movement of the pincer member and presser38, so that prior to each tack driving operation the stock alreadyworked over by the wiper prongs 36, 37, with or without the cooperatingaction of one or both of the gripper jaws 59, 60, will be seized betweenthe advancing presser 38 and the jaw 115 and will be further pulled andwiped upon the sole in position to receive a tack then about t bedriven. A work rest or guide 118 is adjustably secured in a block 119carried by a bracket 120, which bracket in turn is mounted on theraceway 121 attached to the part 10 of the frame carrying the tackhopper 122, as shown in Fig. 7.

I find it desirable to utilize a freely rotating guide Wheel as an edgerest for the shoe when working around the toe and a straight guide restwhen working on the side and shank and therefore I provide means whichwill permit of either of these rests being thrown into or out ofoperative position. Referring to Figs. 1, 2 and 3, a rotatable wheel 123 is mounted on a stud 124 at the end of one arm 125, a similar arm 126substantially at right angles thereto being formed with its end 127 as arest to contact with the work and both these arms are rigidly mounted ona spindle or post 128 perpendicular to the same and adapted to fitwithin a sleeve 129 having a supporting stem 130 held in a bearing 131provided therefor in the bracket 34, a set screw 132 holding the same inadjusted position. The upper part of the sleeve 129 is recessed at 133and a pin 134 secured to the post 128 limits the rotative movement ofthe arms 125 and 126 as said pin traverses the recess 133. When the pin134 is at either end of said recess an arm 125 or 126 is in properposition to engage the work. To hold and lock either arm in operativeposition as desired, I attach rigidly to the bottom of the post 128 anut 135 carrying a lug 136 to which is pivoted a lever 137. Near theother end of said lever is pivotally attached a pin 138 adapted to slidethrough a recess provided therefor in the nut 135 and to engage one oftwo recesses 139 (Fig. 3) in a flange 140 on the adjacent end portion ofthe sleeve 129 to lock the post 128 in desired position. These holes 139are in proper relative position so that the post and consequently thearms 125 and 126 are locked in the extreme position to which said armsand post may be swung, as permitted by the pin 134 and its recess 133already described. T actuate the lever 137 to force the pin 138 intoengagement with either of the recesses 139 when the same are in positionto register I arrange a spring 141 anchored within a bored recess 142 inthe post 128, as clearly shown in Fig. 1. The operator may thus quicklypresent either the wheel 123 or the face 127 of the work rest bydepressing the end of the lever 137, so as to release the locking pin138 from its engagement in the recess in the flame 140, and swinging thearms 125, 126 with the post 128.

In the operation of the machine, the shaft 5 is continuously rotated sothat the wiper bar 26 and, therefore, the wiper forks 36 and 37 togetherwith the side wipers 42 and 43 are uninterruptedly reciprocated. Thepulley 24 is actuated continuously preferably at a less speed than theshaft 5 is rotated. The tack driving cam 23 is fixed to a shaft 6 whichis adapted to be clutched to the pulley 24 and thento be released aftera single tack driving operation, by any of the well known types of onerevolution clutch and brake mechanism. I have not shown this mechanismin detail as it forms no part of my present invention and is an ordinaryand well known mechanism in use in this type of machine arranged to beactuated by a foot treadle so that a tack may be driven at the will ofthe operator. In lasting the toe of a shoe, the operator usually worksfrom the center of the toe along one side, then returns to the center ofthe toe and works along the other side, using first one of the grippers59 or 60 and then the other, as has been explained. In lasting that sideof the toe of a shoe where the shoe is fed from right to left viewingFigs. 1 and 6, for example, the operator positions the shoe as roughlydesignated by dotted lines in Fig. 1, holding the shoe against thebottom rest 118, and resting the side of the shoe against the idler 123,he then depresses the foot treadle connected with the rod 85 to move theratchet wheel 79 and cam 78 beyond the position where said cam holds thearm 58 and gripper 60 out of operative position and also beyond theshort teeth 103. The spring 64 then yieldingly forces the gripper 60into position inside the leather and lining and adjacent to the pincerjaw 115, where it may coiiperate with the prong 36 of the wiper andconstitute a wipinggripper during the lasting of the toe portion. Theconstant reciprocation of the wiper-bar 26 acts to engage and last theshoe as the operator feeds it along and the wide bars 42 and 43 furtherwipe, strain and work the leather toward the point of the upper beingpulled by .the wiping gripper, pushing the fullness away from the edgeand into the best position for being held by the lasting tack whendriven, this continuous lasting action being kept up and tacks driven atintervals until a predetermined number of tacks has been driven and thelever 96 has rotated the ratchet 79 and its attached cam wheel 78 apredetermined distance, as fixed by the number of teeth in a series 104,and again brought the cam into position to engage the roll 105 on therod (58, and throw the gripper'fiO outwardly. The gripper is thenmaintained in outward position as the short teeth 103 cannot be reachedby the pawl on the lever 96. A sufficient number of lasting tacks hasnow been driven, each by actuation of the foot treadle to clutch on thecam 23, to finish one side of the shoe toe. If, however, under certainconditions further lasting of that side of the toe is required, thereciprocating pronged wiper 36, 37 and side wipers 4:2, 13 may beemployed further to treat that side of the toe, and as many additionaltacks may be inserted as are needed properly to fasten that side of thetoe. Furthermore, if desired, the gripper may be again thrown in byoperation of its associated treadle, and the predetermined number ofoperations of the tacker required before the gripper is again thrown outmay be lessened to any desired degree by operation of the treadle; infact, such lessening of the predetermined number may be eifected in thisway at any time, the number of teeth in a series 104, shown as 10, beingselected as probably the maximum required for one side of any toe, Theoperator then swings the shoe around topresent the other side of thetoe, positions it as before with relation to the rest 118 and actuatesthe foot treadle connected with the rod 90 to rotate the cam 74 andrelease the gripper 59 and also to actuate the ratchet wheel 76 to carryits short teeth 103 beyond the other pawl 97 and bring a series of longteeth 104 into position for engagement by that pawl 97 on the lever 96.After a predetermined number of tacks has been driven on that side ofthe toe, the gripper 59 is automatically thrown out, as will be 38 andpincer 115 to last the upper. During I the lasting of the sides of theshank, the edge rest 123 may be shifted and the face 127 of the workrest brought into use. will be understood that in conjunction with thetacking operation the presser 38 moves forwardly as actuated by the arms1 10, 112

and the pincer 115 is actuated to seize and hold the upper intheposition to which it tinuously, until the full stretch of the leatherhas been drawn out, and then a lasting tack driven. At any moment theoperator may swing into use either of the grippers 59 or 60, if desired,and is thus enabled to last entirely around the shoe, utilizing the mostadvantageous instrumentalities at both the toe and heel portions, aswell as at the sides and shank of the shoe, to operate on thoseparticular parts by an instantaneous change at will.
